Without your help in identifying what my dog was allergic too, especially Blue Thomson with Sunflower Oil, he would of continued to suffer with hives, and sever rashes. The vet told me no more steroid shots. I know your tests are accurate as the food I was feeding changed their formula and started using sunflower oil. I immediately saw the return of hives. I would of never known this sever allergy. Thank you so much for making the test affordable. You saved me so much time and torment for my dog.
